+ <p>Provides macros within Apache httpd runtime configuration files,
+ to ease the process of creating numerous similar configuration
+ blocks. When the server starts up, the macros are expanded using the
+ provided parameters, and the result is processed as along with the

+<div class="section">
+<h2><a name="usage" id="usage">Usage</a></h2>
+
+<p>Macros are defined using <code class="directive"><a href="#macro">&lt;Macro&gt;</a></code> blocks, which contain the portion of
+your configuration that needs to be repeated, complete with variables
+for those parts that will need to be substituted.</p>
+
+<p>For example, you might use a macro to define a <code class="directive"><a href="../mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code> block, in order to define
+multiple similar virtual hosts:</p>
+
+<pre class="prettyprint lang-config">&lt;Macro VHost $name $domain&gt;
+&lt;VirtualHost *:80&gt;
+ ServerName $domain
+ ServerAlias www.$domain
+
+ DocumentRoot "/var/www/vhosts/$name"
+ ErrorLog "/var/log/httpd/$name.error_log"
+ CustomLog "/var/log/httpd/$name.access_log" combined
+&lt;/VirtualHost&gt;
+&lt;/Macro&gt;</pre>
+
+
+<p>Macro names are case-insensitive, like httpd configuration
+directives. However, variable names are case sensitive.</p>
+
+<p>You would then invoke this macro several times to create virtual
+hosts:</p>
+
+<pre class="prettyprint lang-config">Use VHost example example.com
+Use VHost myhost hostname.org
+Use VHost apache apache.org
+
+UndefMacro VHost</pre>
+
+
+<p>At server startup time, each of these <code class="directive"><a href="#use">Use</a></code>
+invocations would be expanded into a full virtualhost, as
+described by the <code class="directive"><a href="#macro">&lt;Macro&gt;</a></code>
+definition.</p>
+
+<p>The <code class="directive"><a href="#undefmacro">UndefMacro</a></code> directive is
+used so that later macros using the same variable names don't result in
+conflicting definitions.</p>
+
+<p>A more elaborate version of this example may be seen below in the
+Examples section.</p>
+
+</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
+<div class="section">
+<h2><a name="tips" id="tips">Tips</a></h2>
+
+<p>Parameter names should begin with a sigil such as <code>$</code>,
+<code>%</code>, or <code>@</code>, so that they are clearly
+identifiable, and also in order to help deal with interactions with
+other directives, such as the core <code class="directive"><a href="../mod/core.html#define">Define</a></code> directive. Failure to do so will
+result in a warning. Nevertheless, you are encouraged to have a good
+knowledge of your entire server configuration in order to avoid reusing
+the same variables in different scopes, which can cause confusion.</p>
+
+<p>Parameters prefixed with either <code>$</code> or <code>%</code> are
+not escaped. Parameters prefixes with <code>@</code> are escaped in
+quotes.</p>
+
+<p>Avoid using a parameter which contains another parameter as a prefix,
+(For example, <code>$win</code> and <code>$winter</code>) as this may
+cause confusion at expression evaluation time. In the event of such
+confusion, the longest possible parameter name is used.</p>
+
+<p>If you want to use a value within another string, it is useful to
+surround the parameter in braces, to avoid confusion:</p>
+
+<pre class="prettyprint lang-config">&lt;Macro DocRoot ${docroot}&gt;
+ DocumentRoot "/var/www/${docroot}/htdocs"
+&lt;/Macro&gt;</pre>

+<h2><a name="examples" id="examples">Examples</a></h2>
+
+
+<h3>Virtual Host Definition</h3>
+
+
+<p>A common usage of <code class="module"><a href="../mod/mod_macro.html">mod_macro</a></code> is for the creation of
+dynamically-generated virtual hosts.</p>
+
+<pre class="prettyprint lang-config">## Define a VHost Macro for repetitive configurations
+
+&lt;Macro VHost $host $port $dir&gt;
+ Listen $port
+ &lt;VirtualHost *:$port&gt;
+
+ ServerName $host
+ DocumentRoot "$dir"
+
+ # Public document root
+ &lt;Directory "$dir"&gt;
+ Require all granted
+ &lt;/Directory&gt;
+
+ # limit access to intranet subdir.
+ &lt;Directory "$dir/intranet"&gt;
+ Require ip 10.0.0.0/8
+ &lt;/Directory&gt;
+ &lt;/VirtualHost&gt;
+&lt;/Macro&gt;
+
+## Use of VHost with different arguments.
+
+Use VHost www.apache.org 80 /vhosts/apache/htdocs
+Use VHost example.org 8080 /vhosts/example/htdocs
+Use VHost www.example.fr 1234 /vhosts/example.fr/htdocs</pre>
+
+
+
+<h3>Removal of a macro definition</h3>
+
+
+<p>It's recommended that you undefine a macro once you've used it. This
+avoids confusion in a complex configuration file where there may be
+conflicts in variable names.</p>
+
+<pre class="prettyprint lang-config">&lt;Macro DirGroup $dir $group&gt;
+ &lt;Directory "$dir"&gt;
+ Require group $group
+ &lt;/Directory&gt;
+&lt;/Macro&gt;
+
+Use DirGroup /www/apache/private private
+Use DirGroup /www/apache/server admin
+
+UndefMacro DirGroup</pre>

+<h2><a name="usage" id="usage">Utilisation</a></h2>
+<p>On définit une macro à l'aide des blocs <code class="directive"><a href="#macro">&lt;Macro&gt;</a></code> qui contiennent la portion de votre
+configuration qui intervient de manière répétitive, y compris les
+variables pour les parties qui devront être substituées.</p>
+
+<p>Par exemple, vous pouvez utiliser une macro pour définir un bloc
+<code class="directive"><a href="../mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code>, afin de pouvoir
+définir de nombreux serveurs virtuels similaires :</p>
+
+ <pre class="prettyprint lang-config">&lt;Macro VHost $name $domain&gt;
+&lt;VirtualHost *:80&gt;
+ ServerName $domain
+ ServerAlias www.$domain
+
+ DocumentRoot "/var/www/vhosts/$name"
+ ErrorLog "/var/log/httpd/$name.error_log"
+ CustomLog "/var/log/httpd/$name.access_log" combined
+&lt;/VirtualHost&gt;
+&lt;/Macro&gt;</pre>
+
+
+<p>Comme les directives de configuration httpd, les noms des macros sont
+insensibles à la casse, à la différence des variables qui y sont, elles,
+sensibles.</p>
+
+<p>Vous pouvez alors invoquer cette macro autant de fois que vous le
+voulez pour créer des serveurs virtuels </p>
+
+<pre class="prettyprint lang-config">Use VHost example example.com
+Use VHost myhost hostname.org
+Use VHost apache apache.org
+
+UndefMacro VHost</pre>
+
+
+<p>Au démarrage du serveur, chacune de ces invocations
+<code class="directive"><a href="#use">Use</a></code> sera remplacée par une définition de serveur
+virtuel complète, comme décrit dans la définition de la
+<code class="directive"><a href="#macro">&lt;Macro&gt;</a></code>.</p>
+
+<p>La directive <code class="directive"><a href="#undefmacro">UndefMacro</a></code> permet d'éviter les
+conflits de définitions qui pourraient provenir de l'utilisation
+ultérieure de macros contenant les mêmes noms de variables.</p>
+
+<p>Vous trouverez une version plus élaborée de cet exemple plus loin

+
+<p>Les noms de paramètres doivent commencer par un sigil tel que
+<code>$</code>, <code>%</code>, ou <code>@</code>, de façon à ce qu'ils
+soient clairement identifiables, mais aussi afin de faciliter les
+interactions avec les autres directives, comme la directive de base
+<code class="directive"><a href="../mod/core.html#define">Define</a></code>. Dans le cas contraire, vous
+recevrez un avertissement. En tout état de cause, il est conseillé
+d'avoir une bonne connaissance globale de la configuration du serveur,
+afin d'éviter la réutilisation des mêmes variables à différents niveaux,
+ce qui peut être à l'origine de confusions.</p>
+
+<p>Les paramètres préfixés par <code>$</code> ou <code>%</code> ne sont
+pas échappés. Les paramètres préfixés par <code>@</code> sont échappés
+entre guillemets.</p>
+
+<p>Evitez de préfixer un paramètre par le nom d'un autre paramètre (par
+exemple, présence simultanée des paramètres <code>$win</code> et
+<code>$winter</code>), car ceci peut introduire de la confusion lors de
+l'évaluation des expressions. Si cela se produit, c'est le nom de
+paramètre le plus long possible qui sera utilisé.</p>
+
+<p>Si vous désirez insérer une valeur dans une chaîne, il est conseillé
+de l'entourer d'accolades afin d'éviter toute confusion :</p>

+<h3>Définition de serveurs virtuels</h3>
+
+
+<p>Un exemple typique d'utilisation de <code class="module"><a href="../mod/mod_macro.html">mod_macro</a></code> est la
+création dynamique de serveurs virtuels.</p>
+
+<pre class="prettyprint lang-config">## Définition d'une macro VHost pour les configurations répétitives
+
+&lt;Macro VHost $host $port $dir&gt;
+ Listen $port
+ &lt;VirtualHost *:$port&gt;
+
+ ServerName $host
+ DocumentRoot "$dir"
+
+ # Racine des documents publique
+ &lt;Directory "$dir"&gt;
+ Require all granted
+ &lt;/Directory&gt;
+
+ # restriction d'accès au sous-répertoire intranet.
+ &lt;Directory "$dir/intranet"&gt;
+ Require ip 10.0.0.0/8
+ &lt;/Directory&gt;
+ &lt;/VirtualHost&gt;
+&lt;/Macro&gt;
+
+## Utilisation de la macro VHost avec différents arguments.
+
+Use VHost www.apache.org 80 /vhosts/apache/htdocs
+Use VHost example.org 8080 /vhosts/example/htdocs
+Use VHost www.example.fr 1234 /vhosts/example.fr/htdocs</pre>
+
+
+
+<h3>Suppression d'une définition de macro</h3>
+
+
+<p>Il est recommandé de supprimer la définition d'une macro après
+l'avoir utilisée. Ceci permet d'éviter les confusions au sein d'un
+fichier de configuration complexe où des conflits entre noms de
+variables peuvent survenir.</p>
+
+<pre class="prettyprint lang-config">&lt;Macro DirGroup $dir $group&gt;
+ &lt;Directory "$dir"&gt;
+ Require group $group
+ &lt;/Directory&gt;
+&lt;/Macro&gt;
+
+Use DirGroup /www/apache/private private
+Use DirGroup /www/apache/server admin

+UndefMacro DirGroup</pre>

+ <p>La directive <code class="directive">&lt;Macro&gt;</code> permet de définir une macro
+ dans un fichier de configuration Apache. Le premier argument est le nom
+ de la macro, et les arguments suivants sont les paramètres. Il
+ est de bon aloi de préfixer les noms des paramètres d'une macro
+ avec un caractère parmi '<code>$%@</code>', et d'éviter d'en faire
+ de même avec les noms de macros.
